There was something years ago that claimed to be just that. Not a mechanic in a can but a replacement add pack for engine oil.They advertised don't change the oil replenish the parts of the oil that wear out.I haven't seen it in 35 years. So its of no help whatsoever but thanks for sending me down memory lane.

Carefully balanced formula is designed to complement and enhance the existing API oil formulations.

On the website they recommend it be used with API approved oils for extended drain intervals when mixing with an engine oil. They also have one designed for Hydraulic oils and gear oils, but I'm sure they aren't designed for turning an AW46 hydraulic oil into a functioning engine oil. For that just buy engine oil.

Not long ago I mentioned someone I know who is doing an engine flush with a mix of diesel fuel, engine oil and that additive. His land cruiser is still running the flush (has been for about 4 months) as far as I know it is still running fine, and he's planning on getting me before and after pics so I can post them. (He had such bad sludging the oil pickup screen was almost completely blocked - not to mention the rest of the engine)

Point being even though it may not be exactly what you are looking for, it might be as you call it a toy to play with...

I still wish that someone would make a real, high quality 'TBN booster' type additive as well with; calcium, magnesium, and maybe a good dose of boron, but NO other AW/AF additives, especially not ZDDP.

This could be useful to extend OCIs out until it is possible to do the change, for the very busy folk.

I agree that would be nice, but most calcium and magnesium compounds are multifunctional and double as detergents so I would be concerned that there would be too much surface competition if it didn't have the extra aw stuff to help balance it out.

That said I could see use for a TBN and detergency boost for those who want to do a cleaning cycle for an oil change. I wonder how easy it would be to put somethIng together that wouldn't throw your oil out of spec.

Not too fussed on VIIs or whatever, but a simple AW/detergency package.

The only additive I can think of that I have used in new engines approved by GM istheir EOS additive. My brother had it analysed at his work and it had zinc, calciumand moly. The zinc didn't seem like much but the moly count was high.

^^^I always heard/thought that this additive had sky high levels of ZDDP in it, and not much else, let alone much soluble moly??

Do you have that VOA on it posted anywhere?

No. I never did post it and I don't have it any more. I had heard that the formula changedover the years. I remember it being a very dark liquid. Now it looks like regular motor oil.In the past it probably had more zinc but reduced it now and added moly in it's place. I think it's the best additive out there. It doesn't thicken the oil but adds zinc, calcium and moly to your oil.
